Change in Listing Date: atrazine, propazine, simazine, des-ethyl atrazine (DEA), des-isopropyl atrazine (DIA) and 2,3-diamino-6-chloro-s-triazine (DACT)
On March 27, 2015, the Office of Environmental Health Hazard Assessment (OEHHA) added atrazine, propazine, simazine, des-ethyl atrazine (DEA), des-isopropyl atrazine (DIA) and 2,3-diamino-6-chloro-s-triazine (DACT)* to the list of chemicals known to the state to cause reproductive toxicity for purposes of Proposition 651.
Due to Syngenta Crop Protection’s2 legal challenge to the listing of these chemicals, the effective date of the listing was initially set at August 3, 2015. This was later changed to October 1, 2015. The case has been re-set for hearing by the court on November 13, 2015. Therefore, the effective date of the listing has been changed again to December 14, 2015.
- 2,4‑diamino‑6‑chloro-s-triazine (DACT)
- Des-ethyl atrazine (DEA)
- Des-isopropyl atrazine (DIA)
Footnotes and References
* Note: DACT was incorrectly identified as 2,3-diamino-6-chloro-s-triazine (instead of 2,4-diamino-6-chloro-s-triazine), in the June 12, 2015 notice of proposed rulemaking. That typographical error will be corrected when the chemicals are ultimately added to the list.
